I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

Your System Details show the Total Suspender extension that is probably causing this.

A minimalistic web extension for firefox that suspends natively (with tabs.discard) all non-active tabs and requires only minimal permissions to store it's settings and filter URL's.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Is this about loading tabs when you start Firefox or when Firefox is running and you go to another tab ?

Firefox will detect if your computer's memory is running low, which is defined as lower than 400MB, and suspend unused tabs that you haven't used or looked at in a while. The new tab unload feature is controlled on the about:config page with a preference that you can set to false to disable this feature. Keep in mind that this makes you vulnerable to low memory issues.

  • browser.tabs.unloadOnLowMemory = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Thanks for responding. This is occurring when the browser is open and running. I have done all of the suggested config options. Restarted and it’s still refreshing after 10 seconds of leaving one tab for another. Not sure if it’s a setting in my Mac or not beyond Firefox

Thanks cor-el that fixed the problem! It was still active on my old machine with no problems so that was interesting to find. Thanks for your help
